So, i have been learning about forces, vectors and such. I know many times for convience we break vector forces into rectangular components...fx=Fcostheta, fy=Fcostheta. It is easier to do regular alegbra verus vector alegrba
My question is both fx and fy are scalars, but then they can be negative depending on the angle. How so, arent scalars magnitude without direction, and isn't magnitude a positive value only? Or is magnitude only positive for vectors...scalars can be either?
I see we work with force as a scalar values to represent vectors, can someone please explain this? Just confused is all. Thanks
